It's interesting to me that this text is so different from the text in the Mac version. It's almost as if the two intros were created completely independently of one another, by complete different teams. While that may true, wouldn't they have had access to the same script?! There are some similarities (like the opening line), but some differences that just seem so... different.
(You can see the text of the Mac version in that movie I posted, but for example, the opening lines are "Long ago in the castle of a kingdom called Daventry... Prince Alexander was a young man obsessed." Gives quite a different feeling than "A young prince sits in the throne room, head in hands, lost in melancholy.")
